Sheathmaking: tips and tricks and getting started

Hello all. It's been mentioned above that some folks use drywall or finishing nails for their holes, but I use a larger stitching needle in my running drill press to punch and burnish the holes in one step.
Hi. I have Hirschkleber glue I was intending to use on the sheaths. The instructions are in German. Any ideas on the process for applying this glue.
